To all whom it may concern:

Be it known that I, Go'i'rrRID K NAUs a citizen of the United States, residing at ica o, in the county of Cook and State of Illinois, have invented certain new and useful Im rovements in Machines for Cutting Metal olls, l,of which the following is a. specification.

My invention relates to a machine adapted particularly for cutting diagonal grooves in the perimeters of meta rolls, such rolls, for as are used for rolling tie plates and ormin diagonal ribs on the under side thereof; an the invent-ion has for its object to provide certain novel constructions, arrangements and devices in a machine of this sort which will be hereinafter described and claimed.

The invention is illustrated, in a referred embodiment, in the accompanying. rawings, wherein- Figure 1 is a front elevation of the machine, parts being shown 'invsectiong-.Fi 2, a fragmentary sectional side elevation; ig. 3, va sectional lan taken on line 3-3 of Fig. 1; Fig. 4, a etail .plan view of the cutting apparatus; Fig. 5, ,a section taken through a portion of the roll or collar .supporting device; Fig. 6, a view in pers ective of'a tie plate illustrating the work .t at the nished roll is intended to accomplish; Fig. 7, a fragmentary vertical sectional f view taken through the devices supporting the cutting tool, and Fig. 8, a sectional' p an taken on line88 of Fig. 7.

.Like characters .of reference indicate like parts in the several figures of the drawings.

Referr' to the draw'ngs, lOvrepresents vthe .base o V,the .machine ormed `with the ways 11, 11, in which runs-the reciperocating carriage 12. The carriage may driven by any .desiredmeans have shown the carriage fprovided on its under -side with a rack 13 which is meshed vby a pinion 14 which is adapted to be :driven inany desited manner. Rising from the base 10 -are A 'the uprights v15 connected Yby a .cross iece 1 6, suita 1y zontally movable threaded shaft 18, provided .with a crank 1.9,

L andexten movement of is -revolubvs inears head 17, is involved vin the .contemplated operation vof`the machine.

I The arrangements above described are simply for the purpose of obtaining an initial adjustment.

The head 17 is formed, .as shown, with a boss' 21 :provided with an undercut vertical slot adapted to receive the dovetailed porslides the vertical adjusting slide 33, formed with the pro'ectin llugs 24 carrying rings 25, into wic .are ooked the up er ends of spiral springs 26., the other en s of these springs being hooked into r' 27 carried on brackets 28 attached by olts 2 9 to the, boss 21.

Secured by Abolts 30 -to slide 23 is a circular .member .31 Vformed with a dovetailed ro- ]ection 32 from its front face over w ich Shdes the vertical adjusting slide a3, formed with a lug 34 which .overhangs the dovetailed ortion 32 ofthe circular member 31. 14n adlusting `screw 35 is `revolubly .mounted in lu 34, bein held from `endwise movement y the co lars 36, and .extends into a threaded opening 37 in ,the dovetailed pro- ]ection 32. This arrangement provides for a vertical readjustment of the @tool as the work of cutting proceeds.

Bolted to the adjustingslide 33 is a plate 38, the plate beformed with the curved slot 39 and secure Vto the adjusting slide 33 by a screw bolt This arrangement makes an angular adjustment of the cutting tool possible. Plate .38 is formed with ribs 41, 41 between which is secured, on the pivot 42, the rocking tool holder 43. The 4tool 44 is secured inthe slot in the tool holder by means o f -the set .screw 45. It will be understood that there might be some change in these .details o f construction without deparl ture fromany invention as defined bytheappended claims.

The vmachine' is designed particularly for operating vupon an such ,as .that designated by the numeral 46. In .order to fashion a roll orcollar of lthis sort so .thatt .will form the diagonal ribs 47 on the .under side of a tie 1plate 48 (as shown in -6),;or other simi is necessary to maketwo series of cuts-in the perimeter 1of ,theroll diagonally thereof and transverse with respecttoeach other. With my machine .constructed .and organized, es lby preference I conruct and organize it,

vannular roll or collar ar article, it-

this is accomplished by sup orting the roll in an upright position on tie carriage and in a position oblique with res ect to the travel of the carriage. Preferab y, when the roll is of the annular form shown, it is so supported that after one cut has been made, it may be simply rotated -on the supporting means so as to position it for the next cut arallel thereto. Thisarrangement simplies the cutting operation and gives accuracy to the work, as it is only necessary, for the proper positioning of the cuts, to rotate the collar a distance equal to the intended distances between arallel cuts.

The preferre means of su port is made up of the following parts. A eav plate 49 .is provided having an upright 'we or plate 50 to which is secured a circular block 51. The block has the central threaded pro'ection 52 extendin throu h a boss 53 on plate 50 and secured t ereto y the nut 54. The block 51 is additionally secured to plate 50 by the bolts 55. The roll or collar 46 designed to be operated upon, the inner surface of which has been accurately t-urned so as to fit on the block 51, is secured in the successive positions for making the cuts, by the clamping members 56 and set screws 57 ,v blocks or strips 58 being interposed between the clamping members and the side face of the roll. The roll supporting device, above described, is secured to the carriage 12 in t-he desired oblique position by means of the clamps 59 which overlap the edges of plate 49 and bolts 60, the heads of which 11e in the enlar base or atform of the carriage. After one series o diagonal cuts has been completed the position of the sup ortin device on the collar may be reverse and e other series of cuts transverse to the first mentioned cuts made in the same manner.

I do not claim specifically herein the means for su port-ing the collar as above described, as th are made the Subject matterl of, and are claimed specifically in my ap lication for patent, Serial No. 542,316, filedp February 5, 1910, of which the present applicationis a division.

The diagonal arrangement of the cuts on the circular perimeter of the collar necessitates a vertical shifting of the tool at each cut, dependent upon the angle between the roll and the line of travel of the carriage. This movement of the tool is effected against the tension of springs 26 and its character is determined by a templet sup orted on the carriage 12. This tem let is esignated 63 and is bolted to a stan ard 64-having a foot 65 adapted to be clam ed to the carriage 12 by the clamps 66.v Slide 23 is formed with a depending rt 67 to which is bolted a follower 68 a apted to be engaged by templet 63 when the carriage is moved back and ments 61 of the slots 62 in the ese devices and arrangements support a roll in an u tool, a stationary sup ort on which said forth. This lifts the slide 23 against the tension of springs 26 durin the first part of the cut, and afterward a lows the slide and the tool to move downwardly during the latter part of the cut. On the back stroke the tool carrier 43 can swing a trifle on its pivot 42.-

The operation of the machine will be perhaps very obvious from the foregoing. In rsum, it may be said that when a collar of the sort shown is to be cut, it is iirst clamped upon the supporting device against the vertical plate 50.thereo The templet 63, having been already formed on a proper curve, is clamped to the carriage lengthwise thereof, and thereupon the supporting device for the roll adjusted to the proper anlar position to give the desired cut'. The initial 4cut is made by reciprocating the carriage back and forth, which can be done without attendance except occasionally it willl be necessary to readjust the ad'ustn slide 33. It will be observed that t e too is at all times, within the limits of the spring action, pressed against the work so t at only occasionally adjustment of the adjusting slide 33 is necessary. When the first cut is finished, clamps 56 are loosened and the collar rotated into place for the next cut, whereupon the above described operation is repeated. In order to make the series of cuts transverse to the first series it is only necessary to shift the position of the roll supporting device.

While I have described a preferred form of apparatus forl accomplishing the result desired, it will be obvious that there might be some changes made therein without departure from m invention. Therefore I do not limit mysel to the exact arrangements, constructions and devices shown except so far as certain of these particulars are made limitations on certain of the claims herein.
